The RAD-WHA-1/2NPT Wireless HART adapter simplifies and speeds up the retrofitting and expansion of systems with 4–20-mA signal cables. The adapter is connected to an existing HART device in the field to transfer HART data wirelessly into a new system, while the original system based on just 4–20 mA remains intact. Using the adapter, new field devices are integrated into the network without having to route signal cables. Up to four HART devices can be connected. Independently of HART devices, the adapter can be connected to an individual field device with 4–20-mA output so that a digitized value can be transmitted. — Phoenix Contact, Blomberg, Germany
